GONE-ROLLING MACHINE.

Application ledctober 30, 1926. Serial No. 145,132.

In general, the object of the invention isV to provide a machine ofrelatively compact and inexpensive structure that can be used inconjunction with the most rapidly operating commercial jtype of cakebaking or vwafer baking machine now in use and be so timed in itsloperation as to immediately receive each freshly baked wafer from thebaking machine and forthwith permanently form the wafer into a conicalcontainer.

A further object of the invention is to provide a rapidly operating highcapacity machine capable of holding the formed wafers in a mold underregulated -pressure for a suilicient period of time to insure propercooli ing and hardening or setting of the cakes in the desired conicalform.

A further object of the invention is to provide suitable mechanism forpositively controlling the operation of a series of molds or dies andcooperating mandrcls therefor, so that the pairs of dies and mandrelswill be moved successively to an ejecting and loading position where themandrel is withdrawn from the die to eject the formed cone and is thenreinsertcd into the die, rotated to form a new cone, and held inpressure imposing position within the die unt-il the cone has had ampletime to cool and harden before it is ejected.

An additional object of the invention is to provide mechanism capable ofpositive, rapid and unerring operation, the specific features of whichwill be apparent from a consideration of the accompanying specificatioand drawings wherein: n

Fig. 11 is a perspective view of the opposed carrier blocks mounted onthe end of arm 11.

The machine herein proposed for rolling and molding conicalshapedcontainers from hot moldable wafers comprises a frame 1 thatrotatably supports alongitudinally e2;i tending carrier shaft 2 on whichis mounted a. mandrel carrying member 4 and a mold or die carryingmember that together provide a series of cooperating mold and mandrel'units that are rotated by movement of the shaft 2. This unit,- which ishereinafter sometimes re- I'ferred to for convenience as the moldassembly is intermittently driven from a crank arm 5 that is mostclearly shown in Fig. 4.

The mold or die units 6, are successively moved to a cone ejecting andloading position adjacent a loading apron 7 that successively registerswith the aprons 6a, that are respectively formed adjacent loading slots6b in the side wall of the conical molds. This is shown most clearly inFig. 6. A guard flange'tc is formed adjacentv the other edge of the slot6l to facilitate directing the hot pliable wafers 8 into the lmoldthrough the slot 6b. The rotation of the mandrel 9 draws the wafer intothe mold Where it is maintained under molding pressure as hereinafterdescribed until it is again moved to the ejecting and loading position.The conical discs 9b molds are open at their base and are each removablysecured to the supporting member 3 by a collar or flange 6d to which thebody'of the mold is secured. The mold unit-is preferably formed of sheetmetal. In Fig. 2 the conical mold unit, its associated flanges, and theWafer are shown partially in section.

Referring' again to Fig. 1, each of the mandrels- 9 is carried at oneend of a longitudin ally slida-ble and rotatably mounted bayonet shaft9a that is mounted in bearing supports 4a, carried by the member 4.l Therear end of each bayonet shaft has a control disc 9b that is adapted tobe engaged by a cam operated arm 11 to withdraw themandrel fromthecooperating mold unit and to reassemble the mandrel and mold unit andthereby cause the loading of the mold and mandrel With a hot Wafer. Thecontrol disc .9b is held in position on the shaft by a retaining pin 9c.A helical spring 9d one end of which seats on the disc unit and theother end of Which engages the lateral face of a driving pinion 9e,serves to impose the desired degree of pressure on the formed pastry co1e during the cooling period. A second heli al spring 9*E is alsointerposed between the disc and the drive. pinion for a purpose laterset forth. On each side of the ejecting and loading position of themandrel and mold units, the are engaged by a stationary cam 12, that issupported from the frame 1. Fig. 3 clearly shows the general annularshape of the'cam 12. This cam has a depressed portion 12a that permitswithdrawal ofthe mandrels from the mold units in the ejecting andloading position and retains them in molding position during theremainder of the operating period.

One of the mandrel units is shown in detail in Fig. 9 and Fig. 10. Aseries of ridges aire formed on the conical molding face of the mandrelby Wires 9g, that serve to engage the Wafer to draw .it into the moldingcavity When the mandrel is rotated. The'ridges formed by Wires 9gterminate near the central zone of the mandrel in order that'they maypartially embed themselves in the pastry of the formed cone 8a, andcarry the cone out of the naold When the mandrel is Withdrawn.

A series of spring pressed fingers 13, that are carried by the shaft 2as most clearly shown in Fig. 5, engage the open end of the formedpastry cone- 8, when the mandrel 9 is drawn out of the mold by theoperation of the bayonet shaft. The fingers follow the longitudinalcontour of the mandrel to drag the formed pastry 'cones from the mandreland permit them to fall on the underlying conveyer belt 14. An apron 15and raised side portions 16 confine the -released cones to the surfaceof the conveyer belt.

Having thus generally described the molding and mandrel units of themachine, their cooperative relation and the mechanism for controllingthe coordinated movement of the machine parts Will next'be described.

Power is supplied to the machine through a shaft 17 and a clutchmechanism 18 that is controlled by an 'operating lever 19. Thearrangement of these parts is shown clearly in Fig. 6.- The drive shaft17 is preferably synchronized with the baking machine in order that theWafer baking machine and the cone rolling machine herein described willbe operated in synchronized relation. The clutch unit 18, is slidablycarried on the end of the driving shaft 17 and is driven thereby. Atrain of gears 20, 2l and 22 are driven from thegear pinion 23 that isfreely rotatable on the shaft 17 and that is driven from the clutch unit18. A segmental gear Wheel 24 is keyed to the shaft 20b to which gear 20is secured and the gear Wheel 24 has a smooth periphery except for theseries of serve to engage and operate a cam pinion 25 to intermittentlyadvance the carrier shaft 2 by causing one complete rotation of thecrank arm 5 in the direction indicated foreach revolution of the gear20. After each revolution of the cam pinion 25, the crank arm is held inthe position indicated by the cam face 25 that cooperates With thesmooth peripheral portion of the gear 24. In this \vay, the crank arm 5positively controls the degree of movement of the carrier shaft 2. Thecrank arm 5 swings through the lower 180o zone of its movement beforethe roller 5" that is carried thereby enters between the pairs of spacedparallel cam blocks 26 and 27 that are carried by the mandrel supportingunit 4. During the second half of the rotation of the crank arm, theroller 5 travels radially inwardly along the cam block 26 and therebyadvances the mandrel carrier and the other apparatus carried by theshaft 2 a sufficient amount to move thenext mold unit into registeredpov sition with the supply apron or table 7.

In order to more accurately control the movement of the carrier shaft 2,a band brake 28 that is released only during movement of the carriershaft 2 is provided. One end of the band brake is secured tothe frame 1,and the other end thereof is secured to a cam operated arm 29. Asuitable helical spring 29 acts on the cam arm to normally hold thebrake band taut over the grooved periphery gear lteeth 24L that of themember 4. The cam 30 that is also mounted on the shaft 20b serves tolift the arm 29 during movement of the carrier shaft 2. The Weightofvthe apparatus carried by the` shaft 2 andits speed of operationrenders it desirable to employ a releasable braking 'device to obtainprecise rapid movement of the mold assembly.

A cam 31, that controls the movement of the mandrel operating arm 11,has a cam track 31a that receives a roller 11u that is carried by thearm 11. The arm 11 is pivot-ally carriedby a supporting bracket 32having a guide portion 3.2a arranged parallel with the plane of movementof the arm 11 to engage the side face of the arm 11 and maintain the camroller 11?L within the cam race 31, 1

The outer end of the arm 11 has a pair of opposed V-shaped carrierblocksl 11" mounted in opposed relation thereon to receive thesuccessive control discs 9* of the mandrel ba onet shaft therebetween asthe mold assem ly is rotated. The opening bet-ween thel blocks 11 issuiciently wide to freely receive the controldiscs 9b when the arm 11 isin its forward position with the opening between the blocks in alignmentwith the path of travel of the control discs.

The'cam 31 is so arranged that the arm 11 is in its extremeforwardposition when the mold and mandrel assembly is advanced one step. Thisbrings the control disc 9b between the opposed blocks 11b and alsoopposite the depressed portion 12a of the cam 12.

- After the carrier member 4 is locked into its advanced position by thecrank arm 5, the

' cam track 31a moves the arm 11 .to the posiother wafer into moldingcavity. As the mold assembly is again advanced, the control disc 9bmoves from between the receiver fblocks 11b to a position in front ofthe an nular cam 122L which holds the mandrel within the mold until themandrel and mold are again advanced to the loading zone.

The gear wheel 20 also carries an eccentrically operated ratchet arm 34that serves to advance the ratchet wheel 35 a predetermined distancewith eabch rotation of the gear wheel 20. This controls the movement ofthe conveyor belt 14. The conveyor belt 14 extends around a rotatablysupported pulley drum 35a that is carried by a shaft 35b on which theratchet wheel 35 is also mounted, and thence around a pulley drum 36that is rotatably supported by the frame 1. An idler rofll 37 maintainsthe conveyor belt taut.-

ln the operation of the proposed machine, a freshly baked wafer 8istaken directly from the automatic baking machine (not shown) andplaced While hot on the receiving table 7 in position to be introducedinto a mold unit. The operation of the track cam 31, as heretoforeexplained, draws the mandrel 9 that-'is then in the loading `zone fromits associated mold'. The formed pastry cone `V8a is .carried by themandrel because of the partial embedding of the wire ribs 9bv in thematerial of the cone.` The fingers 13, a pair from which they aremanually gathered upx and packed in suitable containers.

The cam 31 then operates the arm'11 to return the mandrel to itsassociated mold. Because of the weight of the mandrel, a slightlagsometimes develops in the return of the mandrel to its mold. In ordertoprevent too great a lag, a supplemental cushioning spring 9e is broughtinto operation when the spring 9d is compressed a predetermined degree.This insures proper registering of the driven pinion 9e with the drivingteeth of the mutilated gear 33 to rotate the mandrel the ldesired numberof revolutions. Delayed meshing of thetpinion 9e with the gear 33 causesincomplete operation of the mandrel and, as a result, the wafer is notdrawn completely into the mold. The rotation of the mandrel causes themandrel to 'engage the hot wafer 8 to draw the wafer into the conicalmold where yit remains long 'enough to properly cool and take thedesired permanent shape before it is ejected.

The operation of the crank arm 5 causes the mold assembly to bepositively advancedto the succeeding posit-ion which brings the controldisc 9b in front of the cam 12. holds the mandrel in the Ymold under thepressure of the spring 9d. The release of the band brake 28 by the bam30 permits movement ofthe mold assembly by the crank arm andV thereafterarrests the movement without undue strain on the crank arm.

From a consideration of the above de-A scribed cone baking machine andits method of operation, it will be seen that the device 1s This capableof very rapid production of pastry cones for use as containers in thedispensing of ice cream and the like. A very large number of such conescan readily be produced by this machine in a very short time. vIn f act,it has been found, in commercial operation, that the device is capableof forming cones as rapidly as the cakes or wafers can bewbaked in themost rapid form of wafer baking machine now available. v

One of the particular advantages to be enjoyed from practicing theinvention is the shapely appearance of the cone in its finishedcondition. The outer face of the cone is regular and well formed. Theuniform outside dimension of the cones facilitates packing the cones incontainers for distribution to the trade. Another important benefit tobe derived from the invention is the satisfactory closing of the apex ofthe cone in the molding operation. It is very difficult to obtain thisresult on cones formed on the conventional type of molding machine nowin use, so far as applicant is aware. The mal under pressure withig themold vchine herein proposed consistentlygives cones lin which the apexis closed. The commercial advantage of havlng a machine capable offorming a high sugar content cone will be obvious to those skilled inthe art.
